Help/ Bass Cabinet / single 6" speaker

[Barrblues]

I have an old Hughes & Kettner "BATT" Tube preamp that has a 5watt speaker output. It is on my bench right now getting cleaned up, lubed, and loved.
I want to build a little combo with it and a 6" speaker.
I think the Jenson 6" 4ohm would be a great match.
Jensen MOD6-15-4

I have tried cabinet building sites with the software but the cab just does not appear to come out doable. I know there are many great cab designers and freaks in this forum. So please any help would be appreciated.

If I need to add a little horn I may be willing if you make a good argument, but I would like to keep things simple and one speaker would be great.

I know I may be asking too much of a little 6", but I have a little head.

Please, if you want to tell me what a bad idea this is Refrain.

I am sure I am not the first to ask for this or similar help on this forum, but the search engine does not have a crazy filter to find them.

Once again, Any and All Help will be greatly appreciated.
Thanks
Scott

If you just want a little practice combo to fiddle around with at home it might be a good option.
Put that jensen speaker in a sealed enclosure (the Qes is way to high for a ported design). Since the Qes is high the size of that cab doesn't matter much anymore. Keep it around 10 liters or between 0.3 and 0.5 cu ft. It will give you a mid/bass bump but that's ok since the little speaker can not put out real bass.
It has enough highs by itself so I don't think you'll need a horn.
Good luck!

Just a littke sealed box for it. Put some stuffing in there, that's it. Most any speaker can handle 5 watts, doesn't need to be a bass specific driver, or cab.

Thanks Guys
moving forward with BATT mini Combo
Help greatly appreciated

That's such a cool idea! From what I hear on TB, you could probably find a good Faital 6" speaker if you wanted something a bit more modern voiced. I think the Jensen would give you a cool old school (lows rolled out) tone though. If only I actually built that "mini portaflex" I wanted to...

There is nothing quite like using something that you have made. You will enjoy your diy combo amp regardless of the speaker used, but there are more suitable drivers available at relatively low cost. Consider the Aura NS-6, currently available as a buyout at Parts Express for $9.00. It has the same sensitivity as the Jensen, but much lower Fs (55 vs 91Hz) and much higher Xmax (3.9 vs 0.5 mm), and the Qts and Vas will allow some depth to your tone. Just a suggestion.

Good luck with your project.

I would try for something with higher spl considering you have 5 watts. There are 2 Daytons at PE that looked ok

Dayton Audio K165-8 6" Professional Kevlar/Paper Cone Midrange Speaker

Dayton Audio PA165-8 6" PA Driver Speaker

no xmax given but it's got to be a lot higher than the Jensen

for some dough there are 2 very nice ones that I've used

Ciare 6.38NdW - 6.5" LIGHTWEIGHT NEODYMIUM SPEAKER

and

18 sound 6ND430

probably financial overkill

Though it's a nice driver and very cheap it still is no good contender for a ported design (Qes still to high). It could "work" when the cabinet is more then 1 cu ft. It also needs a bit more power to make use of that extended xmax. The BATT needs a simple, light cone driver and that Jensen seems to be a pretty good one for that purpose.

The PA165 looks ok too, it might be possible to make a ported design when the cab size is between 0.5 and 0.7 cu ft, tune it to approx 70hz and you're set.

Hey Arjank do you mind running the numbers on the
Jensen mod 8-20. I think I am heading towards a 8" due to the size of the half rack B.A.T.T.
Thanks

The 8" mod would also use a regular sealed box. Just a little bigger.

thanks I think

[will33]

It's a guitary sort of speaker with a rolled off bottom. It's getting to where every last little cubic inch won't make much difference. I'd just build it to look nice with your BATT, and you'll end up with a decent size box.

[will33]

Probably end up somewhere between 1/2 and 3/4 cu.ft. and would sound nice there.

I think it'd be a pretty cool little amp to put on your coffee table while you sit on your couch and play.


**NOTE**
Just a little pointer. NEVER, EVER use the words "6-inch, and small head in the same sentence. That's not good. No matter how comfortable you are with your masculinity. Just sayin', pal.

[BogeyBass]

yah .7 cubic should be just fine
doesnt really do much more than 2 watts below 200hz.

this is just a 5 watt practice deal, but yah never know.
maybe it will be fine. only concern is after spending time and money to build a custom box, an extra 20 or so bucks might save you extra in the end if you dont like the jenson.

a eminence beta 8 might be overkill for power, but the sensitivity is much higher and it will do 25watts down to 70hz, so speaker distortion is never to be heard.

I was just having a ...little fun... I chose those words for the double entendre. Nice catch but now I know where your mind is at. Very sorry if second meaning applies. For what it is worth I am married and she is NOT running out on me and always walks away happy and slow.

all in fun

I am not looking for hi-fi but definitely low end. Old school and fuzzy farty is cool with me. Got to have the low end. I appreciate ALL suggestions but at some point i am going to half to commit to a speaker.

Can I build a general sized cab and get the performance from different 8" speakers that you guys are going to send me to try?
By the way I will return them with only 5watts pushed thru at most. shipping cost on me.

[Barrblues]

porting vs sealed vs open back/partial open back?

8ohms vs 4ohms? dont see the beta 8 in 4 ohms.
